26
27   Parameters:
28       map=name
29           Name of input raster map
30
31       conf=string
32           Configuration file
33
34       output=name
35           Name for output raster map
36

DESCRIPTION

38       r.li.padrange (patch area distribution range) calculates as:
39       with:
40
41                     amax: max patch area size
42
43                     amin: min patch area size
44

EXAMPLES

46       To calculate range of patch area size, using my_conf configuration file
47       and saving results in my_out file run:
48
49       r.li.padrange map=my_map conf=my_conf output=my_out

NOTES

53       Do  not  use  absolute  path names for output files. They are raster if
54       moving  window  disposition  was  selected,  otherwise  they   are   in
55       ~/.r.li/output folder.
56       If  input  raster  is  not  full of null values r.li.padrange returns a
57       value >=0 that is PADcv.
58       If input raster is full of null values r.li.padrange returns -1.
59       If you want to have null values instead run
60
61       r.null setnull=-1 map=my_map
62        after index calculation.
